FIGURE T31. Pressure-latitude section of
the mean (top) and anomalous (bottom) zonal wind and divergent
circulation over the west Pacific sector (120°E–170°E). The
divergent circulation is represented by vectors of combined pressure
vertical velocity and divergent meridional wind. Shading and contours
denote zonal wind (m s-1).
Anomalies are departures from the 1979–95 base period monthly means.
